It's an original Ark Royal and Tribal Class from Revell. They were always boxed together and even the box art seemed to go on for the life of the kit.

They are both waterline models and look quite nice. A touch heavy by modern standards, but the photo speaks for itself.

The box art shows Ark Royal sinking and a tTribal standing by. In the real photos, it's always HMS Legion in shot, not a Tribal. As these kits are quite old and not top of the hi tec line, they seem to appear on second hand kit stalls at shows. No idea what they're going for now though.

Revell invented 1/720 scale in the late 1960s (Ark & the Tribal was the only RN kit they did). Italeri used the scale for their ship kits because Revell were distributing them in Germany and the UK at the time.
